Description

Seawater electronics shrimper

Technical field

The utility model relates to fishery and fishes for matching used electronic jamming utensil, specifically is a kind of seawater electronics shrimper.

Background technology

What fish in the seawater that shrimp adopts always is that fishing net is fished for measure, because the behaviour area of shrimp is many at seabed mud bank place, traditional fishing net is fished for and just seemed very difficult.China Patent No. 200420150251.X discloses a kind of " energy-efficient electrofishing device ", and its circuit has adopted the multichannel control button, and control impuls oscillating circuit, power amplification circuit convert 220V to by transformer then and exchange and to output to catching device respectively.Though this circuit is simple than electronics contravariant circuit, still do not break away from the electric shock mode that direct current converts interchange to.And the habit of shrimp is different from the fish that moves about in the water, this high-frequency continuous electric shock, and electric current is excessive to be hit shrimp extremely easily at the bottom, and electric current is little and inoperative.

The utility model content

The purpose of this utility model is exactly the defective that exists at prior art, provides that a kind of a kind of circuit of developing at the life characteristic of the conductive characteristic of seawater and shrimp specially is simple, direct current is interrupted the seawater electronics shrimper of the electric shock way of output.

Its technical scheme is: comprise that DC power supply, impulse hunting and power amplification circuit, transformer, rectification circuit, filter circuit, thyristor gating circuit, high-voltage output end connect to form successively.Also connect switch at power output end.

Described impulse hunting and power amplification circuit are to be connected and composed by plural triode, described rectification circuit is a bridge rectifier, filter circuit comprises two electrolytic capacitors formation in parallel at least, and thyristor gating circuit is the bidirectional triode thyristor circuits for triggering.

Effect of the present utility model: the characteristics of the utility model circuit are that direct current changes into high pressure, low frequency DC power supply, and circuit is simple, handling safety, convenience, and volume is little, in light weight, and power consumption is few, is particularly suitable for the shrimp electric shock of living in the seawater bottom is used.

Description of drawings

Accompanying drawing is the circuit theory diagrams of a kind of exemplary embodiments of the present utility model.

Embodiment:

With reference to accompanying drawing, comprise that the anodal direct current 12V of storage battery power supply is through diode D5, transformer B1, insert the triode G1 and the G2 collector electrode of two parallel connections, insert the triode G1 and the G2 base stage of two parallel connections behind the transformer B2 series resistance R1, connect the negative pole of storage battery after the triode G1 of two parallel connections and the emitter parallel connection of G2, constitute impulse hunting and power amplification circuit.After the secondary B3 of transformer B connects the bridge rectifier of four diode D1, D2, D3, D4 composition, be connected to the filter circuit of two groups of capacitor C 1, C2 composition, form circuits for triggering by resistance R 2, bidirectional diode D6 and controllable silicon SCI, give lead-out terminal (connecting the catching device electrode) output high voltage direct current.

Can also also connect switch at power output end in the foregoing description, so that the control power work.

Its operation principle is: the storage battery positive electrical diode D5 that flows through, transformer B1 is to G1, the collector electrode of G2, transformer B2 induced voltage is given G1 through resistance R 1 simultaneously, conducting voltage of G2, emitter connects the negative pole of storage battery, power amplification triode G1, the G2 conducting, form a stronger voltage at the B1 two ends, transformer secondary output B3 two ends produce ac high-voltage simultaneously, through the D1-D4 rectification, become direct current and give capacitor C 1, the C2 charging, control charging interval 4-5 capacitor C 1 after second, C2 produces high pressure 200-300V, controllable silicon SCI conducting, capacitor C 1, the high-pressure energy outburst output that C2 stores, in seawater, produce high-tension current, shrimp is hit from the seawater bottom, fish for net then.After the high pressure output, the SCI control utmost point loses conducting voltage, and high pressure output stops, and rectification circuit, discharges after the arrival certain voltage once more once more to the electric capacity charging.So continuous circulation is shocked by electricity at interval to the shrimp at the bottom, and shrimp just falls into fishing net easily.

Claims
